Modify Menu bars - no VBA (Excel 2000)

I am trying to analyze a workbook that I received. It modifies the Excel menu bars when it is loaded, and I would like to change the code. I reviewed the VBA code carefully, and this workbook appears NOT to use VBA code to modify the menu bars.

I extracted one small sheet, and deleted all the VBA code modules. I saved this as a stand-alone workbook. When I load it into Excel, I do not get any "VBA macro" warning. But it still changes the standard Excel menu bar!

Does anyone know how to do what this workbook is doing? I am hoping someone has run into this behavior before. My brute force approach is to undo all the menu bar changes, and start over:

Apparently menu edits that were made with the Excel 5/95 menu editor can not be modified by Excel 97/2000. Jim Rech has created an Add-In named "Remove Menu Editor Edits" that will remove these menu edits. I tried it, and it worked!

Now I can start with a "clean slate". Thanks for pointing me in the right direction.
